IOWER-APPLYING DEVICE.

Application filed January 9, 1925. Serial No. 1,332. i

This invention relates to power storing and applying devices, andit has particular relation to a device of the character designated wherein a .constantly, or-substantially constantly, applied small amount of power is transmitted through a system of novelleverages and stored to accumulate alarge amount of potential energy, the last mentioned energy being utilized for various purposes.

The apparatus which-is hereinafter deferent associations to obtain the required storage of energy and application of power and, although the applicationof the device is described in connection with an intermit-' tently applied force such as may be taken from a particular mechanical device capable of delivering power, it should be understood that the invention is capable of use in connection with many different mechanical apparatuses such, for instance, as drop-hamn'iers, timers for the flow of materials, time-locks, time-controls for furnaces, speed indicators and measuring devices, jacks of all kinds,

r adding machines, and any other mechanisms whereinit is desired to periodically indicate conditions which have occurred over a space of time, or changes of condition after a period of time. v

A further-object of my invention is to provide a device of the above character wherein the operation is effected by gravity, and the stored-up energy of spring devices does not have to be relied upon. A device of tltie'character hereinafter described is,.therefore,,far

} more accurate and positive in operation.

The invention will be better understood by reference to the accompanying drawings, in which: 1

Figure 1 is a perspective ,elevational view of a preferred form of mechanism en'ibodyin g the invention;

Fig. 2 is'a plan view of the apparatus shown in Fig. 1; i

Fig. 3 is an elevational view of a portion of the device illustrating one feature thereof which especially contributes to the desirabit.

ity and accuracy of operation of the device; Fig. i is an elevational, sectional view taken. fromone side of the device, tlns side being the backside of thedevice as shown in drawings, the devicein the preferred form shown, may embody two plates 9 and 10, said plates being connected together near their top by beam-like members 11 and 12 whereby a rigid frame is eventuated for the device.

In. Fig. 1 the device is shown in perspective, and in so doing plate 10 is entirely removed, it being understood that, as viewed in Fig. 1,-we are looking at that side of the machine which is at the top in Fig. 2. It will further be understood that the various instrumentalities which are hereafter de scribed, such as shafts and beams, and which. extend from plate to plate and are journalled therein, extend through, or to, the plate 10 which has been removed in Fig. 1.-

A shaft 13 extends between the beam mem bers 11 and 12, and is supported through precision bearings 14 and 15 respectively (Fig. 5) set into said beams. Mounted on the shaft .13 is a worm 16, which latter engages a large gear wheel 1.7. This last named gear wl'leel 17 mounted on a shaft 18, which latter is journalled in precision bearings set into the side frames 9and 10, these being ofthe same character as is illustrated in connection with the shaft 1.3. There is, therefore, an initial nmltiplication of mechanical adval'ltage by the worm and wheel. lVlnle a worm is de scribed and hereafter referred to, it should be understood that a spiral gear may be used if desired instead of a worm without departing from the scope of the invention.

in both directions. The purpose of this inequality of disposition of abutments will be hereinafter explained-,and it should be now noted that thisis one of the particular features of the present apparatus which commends it for use in connection with an. indi- -measuren'1ent between them is not the same eating mechanism, for instance with meters ofva'rious types whereby an accurate indication of the amount of materialmetered Wlll be obtained, even though the mechanism herein described must, of necessity, take some time to register.

- An angular arm, 23 is pivotally mounted 1n the frame members 9 and'10-on24,-"said arm having a segmental gear 25 formed integrally therewithx Then Wardly extending portion 26 see Fig. 1) of the jat'oresaid 'arm termi--' nates in a planer bearing member 27 upon which the rollers "21 -and'22 ma'yride:

If both dogs occupy'the same osi tion with respecttothe rootor base *the" tooth,there is a possibility of lost motion to theex'tentof'one ratchet tooth, particularly-if l k dly shaft 30.

botli pawls'should' happen to starttheir actuating movementatthe apex; of the two teeth which said pawls areabout toengage; How-- ever-, whent'oue pawl is set-at the-apex of a r tooth 1 and the other about half-way between the apex andba seof a tooth the totalpossible vlost mos-0111s one-half tooth only. The provision of two pawls, therefore, and thesetting of 'thessame as just described eventuat'es a very ac'curatema'chinein that lost motion is substantially reduced and-' also gives a measure of safety to themachinef.

A weight 33 is mounted'on pins 33" and 33" lIl'lZhBSldG frame and has-"teeth thereu'pon' i the upperlimit Whiehenga'ge' with the teeth of the segmental geari whereby a downward movement -of the arm 23 functions toraise said weigh-t- 33 'to' of it ovement '(see'F igg andfi);

The operation of the improved device is as follows,- it being asumed for purposes of illustration only, that the power storing and applyingdevice embodying the elements above described, is used in connection with some sort of device which has an intermittently or constantly moving member, and where it is desired to accumulate the small increments of'e'nergy received from 'the intermittently or constantly moving member into a considerably greater power, 'whichlatter is periodieally'ir'nparte'd to the work'shaft, fort 1is purpose it is assumed that a member34 is 'inter'-" wheel 36."

The worm" 16 is, therefore, lnterniittently turned 'and 'in 'so doingturn'sWhe wheel 17.

As the latter turns; the rollers'21 or 22-"press the arm'23' downwardly around't'he pivot 24, "and through the 'intermeshing of the segmitten'tly or constantlymovable to actuatethe' 'wo'rni- 16 through a -dog and a ratchet mental gear 25 and the teeth on the weightB3; the latter is raised and the energy thus trahs mitted is stored for "future application.

WVhcnthe-arm 23has reached its lowermost l position, the "rollers 21 or 22' ride oif 'the in-" nor end of the bearing surface 27', thereby re leasing the arm and allowingtheweighe33 to 'pull the arm" upwardly. As the'arm travels downwardly, the dogs 32 ride 5 overteeth 31-and no movementis communieated'to the aforesaid teeth 31, or the gear 28 rigidly' 1 secured"to'the latter. \Vhem-however', the

*weight moves' downwardly under the 'influenee of gravity, it being remembered that this latter occurs whenthe 23 is released,

31 and quickly turn'the' gear28' in a block-' thedogs '32 engage the teeth on'the member wise direction (Fig. 1), the turning of' this 1 gear in turn rotates the small gear wheel 29 "and the work shaft 30: -It follows, therefore,

that the power, which, through substantially theh'alf revolution of the gear 17 ,has been gradually stored up as received from the intermittentmotion of the member '34, is

multiplied and applied to" the Upon the Shaft 3O, therefore," may be desired to move through application"ofan intermittent-but constantly applied 'force' on i -mounted any instrumentalitics which 'itis the shaft 13. As hereinbeforeindicated, the

abutlmnt's 19 and 20 are not ina diametrieal line for the reason that an appreciable time is takenwhile thearm moves'"back up into juxtaposition with the next roller, audit the 1 abutments or rollerswere exactly opposite" each other an error would result, since thatquant-ity of'movement which "occurred on shaft 13 during the return of the arm would be 10st. However, b arranging the rollers as described, in that t ey are not seated along a dian'ietrieal-line, this loss is prevented since the same is compensated at every complete revolution of the wheel 17. In other words,

what is lost during one interval of arm oper- As hereinbefore indicated, the shaft may carry various instrumentalities, and since the inertia of these may be such that the shaft 30 is not stopped at the desired point when the arm returns to its upward position, a mechanism for insuring an exact 360 revolution of the shaft 30, but no more, is pro vided, as illustrated in Fig. 3.

Keyed to the shaft 30 is a lug or stop 37 which, while the shaft 30 is in stationary position, 1s disposed downwardly, as shown ,in Fig.3. A pin38 is fixed on the Weight33,

which pin, upon the raising of the weight,

strikes against the right-hand end 39 of the pivotally mounted lever 40. The lefthand end 41 of lever 40 is against thelug 37 whereby the shaft is positively prevented from.

turning in an anti-clockwise direction as long as said lever 40 is in the position shown. Immediately, however, before the weight 33 reaches the uppermost position and the arm 23 is released and starts to return to the position shown in Fig. 1, the pin 38 strikes the lever 40 and turns it so that the lefthand end 41 thereof is no longer in the way of thelug 37. The shaft 30 is then free to be turned by downward movement of the weight33 and the consequent movement imparted to the gear 28. Immediately, however, the pin 38 releases the lever 40, the latter, by reason of the end 39 being weighted, moves downwardly into the position shown in Fig. 3 and occupies that position before the shaft 30 has an opportunity to make a complete revolution. Since thelever is, therefore, in the position shown in Fig. 3, the shaft- 30 will be positively stopped upon the completion'of one revolution. cussed in the above description it is apparent that a plurality of such shafts may be moved by the gear wheel 28,wherebyniore thanone set of mechanism may be actuated through the latter.

In order to further insure a positive return of the shaft 30 to the proper position, there is provided another Weighted and pivoted lever 44, which may turn about a pivot 45, because of its weighted end 46, as the weight 33 moves upwardly. A pin 47 normally holds the lever 44 in the position shown in Fig.3, in which position an elongated lug 4S bears against the lug 37 and holds it positively in the position shown.

In the operation of the device, as the weight 33 moves upwardly the pin 47 releases the lever 44 and allows said lever to swing, under the influence of the weighted end 46, so that the upper end of the lug 48 is Withdrawn from the circular path of the lug 37. A pin 49 is positioned at the left of the elongated member 48. When the upward movement of the pin 47 allows the member 48 to swing to the left, the latter rests against the pin 49.

l/Vhile but one. shaft 30 dis- When, therefore, the weight 33 moves downwardly thepin 47 moves the lever 44 back into the position shown in Fig. If the shaft 30 .l

for any reason should not return all the .way tothe position shown in Fig. 3, the upper end the elongated lug 48 engages the lug 37 on said shaft 30 and positively moves it into the position shown in Fig. 3, this positive movement being effected by the pin 47 moving the lever 44 down *ardly. y

While the shaft 13 is described as rotated through the cooperation of an intermittently or constantly movable member 34, a dog 35, and a circular ratchet 36, it should be pointed out that this apparatus may be further elaborated to provide for movement through still another storing means, this last named structure being shown in Figs. 7 and 8. i In theselatter figures the dog 35 is illustrated as. being pivotally mounted on the lower end ofa lever 42, this latter is pivoted on a mem- I ber 43. securedto the framemember 9. The intermittently or constantly movable member 34 is secured to the upper end of the. lever 42, and it will be seen that by this method the force applied can be again multiplied in this ratio, which ratio may be still stood that the foregoing device is a unitary self-contained apparatus which may be applied to a variety of different uses, and it is desired, therefore, that the invention disclosed be restricted only by the appendedclaims and by the scope of the prior art.
